Led Grow

[Cultivate420]

The blue/red led light makes the plants mag hungry and it shows up on the petoiles, every strain Ive grown under pink led has had purple petoiles.

If i may ask what nutes and feeding cycle do you use? Are you in coco? Do you take extra care to provide more mag? I was going hard on the Calmag with 2ml per gallon of water. feeding twice a day in coco perelite mix 3 g smart pots with AD coco part A B bloom based nutes. I cut of the CalMag because it has too much Nitrogen but i don't wany to run in to deficiency so any preventive advice is greatly appreciated.

I run 5ml/gal of calmag until the second or third week of flower then switch to budswell, my petoiles are still purple, especially the ones closest to the light. I think its the Ir or Uv that does it.

The wattage pulled from the wall is your out put. the manufactures stated wattage is just a marketing ploy.

It is hard to estimate anybody's yield, because of so many factors involved.
Not only is the wattage taken into the fact, but the distance from canopy, strain, if topping/lst involved, type of medium, nutrients and experience of grower...etc.etc...
The bench mark was about .5 grams per watt, some peeps have done the 1 gram watt... but really the most important is Quality...
IME... leds cause bushier plant, so sometimes I need to raise the lights farther than I normally would just so I can have space between internodes. hope some of this helps

That's what I'm finding out to. I had my light 18 inches above the canopy for the first three weeks and the plants were six inch little bushes. I then raised my light to three feet above the canopy and that's when the plants started to grow finally. Now there three weeks into flower and sitting about two feet under the light after some stretch. Point being the plants have been much happier with the light being raised above 18inches imo.

I agree, I have similar results

That's what happened to my girls in the beginning. Been giving them a small dose almost ever watering

Here's mine with the purple stems. I'm going to keep giving them what I've been giving them and see what happens. My profile is 100N-60P-116K-61M-97Ca-67Su-12Si. Once I switch over to raw fertilizers I can make my own profile and bump up cal mag without messing up the other ratios.

Peeps don't realize that too much light on youngins can be a negative. Unless your doing an extensive finning. super cropping and training that the tight interdodes may help. That close light is a form of stress imo.

The two most important things I've learned this grow, being my first indoor grow and with a cheap red and blue led are as follows: 18 inches above canopy for plants younger than a month is to close, three feet worked good for me. Second most important thing is your plants under these red and blue lights starve for cal/mg. Thank you forum:)
